CK-101 Lab 03 – Lab Report Name: Will Stransky Experiment 3: Properties of Gases Questions within procedures: 1. Hydrogen G. When hydrogen gas comes in close contact with fire‚ it generates a loud noise similar to a popped piece of popcorn and it blows out the flame. 2. Oxygen B. When manganese reacts with H2O2 small bubbles form around the pieces of manganese and carbonates the whole solution. E. When I put the glowing toothpick in the oxygen gas it caused

January 23rd‚ 2013 Generation of Hydrogen Gas Abstract Hydrogen gas was produced from a reaction in a eudiometer between a weighted amount of magnesium ribbon and 5ml of diluted 6M hydrochloric acid. The partial pressure of the hydrogen gas produced was calculated using Dalton’s Law of partial pressure. With this partial pressure value along with known values in the experiment the number of moles of hydrogen gas produced could be calculated using the ideal gas law equation and this experimental

Chemistry Lab Report (Redox Reactions) Questions: • What will happen when you put zinc in copper II sulfate? • What will happen when you put copper in copper II sulfate? Predictions: • We can predict that zinc will react with the aqueous solution of copper II sulfate and we will notice a reaction. We can also predict that the copper will not react with the solution of copper II sulfate and no reaction will be noticed. Hypothesis: • It is hypothesized the zinc metal will have a precipitation reaction with

Photosynthesis (happens in chloroplasts in mesophyll cells) 1. Light dependent stage Happens in the grana of chloroplasts Light (energy) gets trapped by chlorophyll pigments (light energy converted to chemical energy) This energy used to turn ADP and Pi into ATP Energy used to split water (H2O) into Hydrogen and Oxygen The hydrogen ions get collected by NADP‚ which becomes NADPH The Oxygen is waste‚ and leaves! So‚ in this stage‚ water comes in. ATP and NAPDH come out‚ as does Oxygen.

Catalase Experiment Research Question: How does the weight of a piece of liver (0.4g‚ 0.8g‚ 1.2g and 1.6g in this case) affect the amount of gas created after 2 minutes when combined with hydrogen peroxide? Aim: To see find out how the amount of catalase correlates with the amount of gas created when in combination with hydrogen peroxide. Materials: 15g of liver 25 ml of hydrogen peroxide 1 scale 1 bucket 1 100ml graduated cylinder 1 250ml flask with bung 1 50cm tube (able to fix onto top of flask)

Zinc oxide in a mixture with a about 0.5% iron(III) oxide (Fe2O3) is called calamine and is used in calamine lotion. There are also two minerals‚ smithsonite and hemimorphite‚ which have been called calamine historically (see: calamine (mineral). Zinc peroxide‚ ZnO2 .½ H2O‚ is a white to yellow powder that is used in antiseptic ointments. Zinc white is used as a pigment in paints and is more opaque than lithopone‚ but less opaque than titanium dioxide. It is also used in coatings for paper

What happens in diabetes? Lack of insulin or a resistance to insulin is known to have major metabolic effects. Food powers our bodies. When we eat food‚ most digestable carbohydrates are converted into glucose and rapidly absorbed into the bloodstream. We use this glucose for energy. However these carbohydrates cannot be utilized effectively and excess glucose cannot be stored in the liver. The glucose level in the blood increases but the cells of the body will be lacking of glucose and energy.

What Happens Next Caitlyn Smith I woke up early one day. The cave was dark and I could not see. I went outside to see if I could find mother‚ but she was nowhere to be found; I guess she went off somewhere without telling me. I’m looking around after just waking up and I see this creature. I don’t know what to do. He comes closer‚ what am I supposed to do? I saw him running towards me and I started getting scared. He grabbed a stick and threw it towards me as if to warn me that he was
